HYDRAULIC M OTOR.

SPECIFICATION forming part of Letters Patent No. 296,381, dated April 8, 1884.

Application filed November 19, 1883. '(No model.)

To wZZ whom it may concern:

Be it known that I, Hnnimmv BAUMOTTE, a subject of the King of Prussia, residing at the city of Vossnaiken, (near Kupferdreh,) in the Kingdom of Prussia, GermanEmpire, have invented certain new and useful Improvements in Hydrauliclliotors, of which the following is a specification.

This invention has reference to certain improvements in the hydraulic motor for which Letters Patent have been granted to me heretofore, under date of October 9, 1883, No. 286,374, said improvements being designed to furnish aduplex motor, or a combination of two motors coupled together in one system, with a view to give greater steadiness to the motor, make its lateral movements easier, and utilize in a higher degree the water-current in its entire width without increasing the bulk of the apparatus.

My invention consists, primarily, of a floating frame with two paddlechains, which are arranged at an angle of inclination to the direction of the current, while the paddles of said chains are supported at right angles to the current, so thatthe full pressure of the water-current acts directly upon the surface of the paddles; secondly, in providing the paddle-chains with duplex anti-friction rollers, to

reduce the friction of the chains in their guideways; thirdly, by connecting thefloating frame of the motor at two points with an intermediate chain, and thelatter to an anchoring-chain, so as to impart steadiness againstlateral sway to the motor; fourthly, by connecting the float ing frame, intermediate chain, and anchoringchain with a motion-transmitting chain and gear, so that the motor can be shifted laterally out of the way of vessels without disturbing the anchorage; and, lastly, in the arrangement of end gates or deflectors at the rear end of the motors, which direct the current against the paddles, and augment thereby the effective water-pressure upon the same.

In the accompanying drawings, Figure 1 is a cross-section of the endless paddle-chain and its guideways. Fig. 2 is a plan of part of same, showing two paddles and the means by which they are held in position. Fig. 3 is a side view of apart of the chain, showing one of the guiding and stretching sprocket-wheels.

Fig. 4 shows a modified construction of the paddlechain. Fig. 5 is a detail cross-section of a guideway and a part of the chain with its anti-friction rollers. Fig. 6 is a plan of my improved hydraulic motor shown as anchored, and Fig. 7 is a detail sectional side elevation of the steering-gear.

Similar letters of reference indicate corresponding parts.

In the drawings, E E represent transverse beams, which are secured to floats E E. To the beams E E are secured the supportingframes D D of two hydraulic motors, M M, each of which is composed of an endless paddle-chain, a, having a number of paddles, a c. The paddle-chains a are formed of pivoted links which pass over stretching sprocketwheels 0 o, the shafts p p of which are sup ported in bearings of the frame D. The pad: dle-chainsnn move on guideways of the frames D D. These two paddle-chains dip by their paddles into the water, and are arranged at a suitable angle of inclination to the longitudinal axis of the motor. however, not arranged at right angles to the direction of motion of the chains, butat right angles to the direction of the current. They extend, therefore, diagonally across the chains,

The paddles a a are,

corresponding to the angle of inclination of so in Fig. 4. In both constructions the paddle chain consists of two endless link-chains united at regular intervals by cross-bars b b, to which the paddles are attached, In one construction the cross-bars b b are arranged at right angles to the chains, and the paddles a a are attached rigidly to the cross-bars, but at an inclination thereto, which inclination corresponds to the angle of inclination formed by the axis of the chains to the direction of the watercurrent. In the other construction the cross-bars are provided with short end por tions at right angles to the chains, while their main or middle parts are inclined or diagonal to the axis of the chain and have the paddles directly attached to them.

In order to secure the paddles in position,

they are braced by inclined stays m, which connect each paddle to the crossbar of the next following paddle. In Figs. 1, 2, 3 each stay at consists of a. metallic rod, which is secured by a sleeve to the middle of the cross-bar b, and extended at its outer end through a slot, a, in the paddle. The stay-rod m is provided at its outer end with balls or other projections, a", between which the paddle is located, so that they permit a certain degree of play when the paddles are moved with their stays over the sprocket-wheels. In the construction shown in Fig. 4 the ends of the diagonal cross-bars b 12 do not form pivots of the chain-links, but are applied to openings or sockets of the latter, their paddles being held in position by ropes or chains m, which pass through two openings, a, of the paddles, and are fastened at their ends to the cross-bar of the next following paddle, as shown in Figs. 4 and 6. This arrangement gives the paddles the necessary strength to resist the water-current, but does not dispense with the stay-rods m, which prevent the turning over of the paddles when they are lifted out of the water. By either of these constructions the paddles can be arranged at the required angle of inclination to the chains, while a certain degree of play is imparted to them as they pass over the sprocket-wheels.

In order to diminish the friction of the paddle-chains in their guideways q, the end of each crossbar b is provided with two anti-friction rollers, 0 (Z, which are clearly shown in Fig. 5. The larger of these rollers, 0, takes up the friction exerted by the weight-ofthe chain, and is placed by its hub loosely on the end of the cross-bar b, said hub abutting against a fixed collar, 2), of the cross-bar b. The roller 0 has 011 its outer end a cavity, 0, which gives room for a key-piece, d, that carries a second smaller roller (1, the axis of which is at right angles to the axis of the larger roller, 0. The roller d takes up the lateral friction in the ways, which is due to the diagonal arrangement of the paddle-chains.

In order to utilize that part of the watercurrent which would otherwise pass through without effect between the rear ends of the converging motors M M, said rear ends are connected by forward-projecting gates, h h, which meet in the center line of the entire structure. These gates divide the water-current in the middle and deflect the so-divided current onto the paddle-chains of both motors M M.

The apparatus as described is anchored in the water-current by means of two chains-a connecting-chain, 43 t, and anchoring-chain, f fand an intermediate steering or adjusting device, G, which is worked from the frame of the motor by means of an endless chain, G. The ends of the connecting-chain i i are fastened to two points, a: w, on the front beam, E, as far apart from each other as possible, whereby the entire structure acquires a greater steadiness and becomes perfectly self-adjusting in the current. The intermediate Steering or adjusting device, G, is attached to the middle part of the connecting-chain i t", and engages by means of a small sprocketwheel, j, with the anchoring-chain f f, both ends of which are anchored separately at a suitable distance from each other. The sprocket-wheel f is keyed to the shaft of a gearwheel, f into which meshes a pinion, f", 011 the shaft of a second sprocket-wheel, f which is turned by the endless. steering-chain G, that passes over a sprocket-wheel, g, on a shaft, supported in bearings on the front beam, E. The shaft 9 of the sprocket-wheel g is turned by a crank-shaft and gear-wheel transmission whenever it is desired to shift the entire motion from its normal position at the center line of the water-current to one side or the other, so as to move it out of the way of vessels. By this steering mechanism described, the sprocketwheel f is made to 'travel along the anchoring-chain ff in one or the opposite direction, whereby the entire motor is moved to one side or the other without disturbing the anchorage, as shown in dotted lines in Fig. 6. To assist this lateral movement of the floating motor, thehind floats, E, are provided with adjustable rudders g, which by the force of the water-current accelerate the lateral motion imparted to the motor by the steering device.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a hydraulic motor, the combination of a floating main frame, converging auxiliary frames arranged symmetrically to the direction of the current, and endless paddle-chains mounted on sprocket-wheels of said auxiliary frames, the paddles of said chains being arranged diagonally to the axis of the chain and at right angles to the direction of the current, substantially as set forth.

2. In a hydraulic motor arranged at an angle to the direction of the current, the combination of a supporting frame, longitudinal guideways, apaddle-chain mounted on sprocket-wheels of said frame, and lateral paddle-bars having anti-friction rollers at the ends, one roller being made larger and the second roller being arranged with a cavity at its end, the sec ond roller being arranged in said cavity and at right angles to the axis of the larger roller, substantially as described.

3. In a hydraulic motor, the combination of two symmetrically arranged converging paddle-chain motors with forward-extending water gates or deflectors located between the rear ends of the motors, said water-gates being connected to each other, so as to divide the current, substantially as set forth.

In a hydraulic motor, the combination of floating paddle-chain'motors and an intermediate chain attached to two points at the front ate front chein attached to two points of said frame, an anchoring-chain connected to the center of the intermediate chain and anchored at both ends, 4- steering or adjusting chain ex- 5 tending from the motor-frame to the point of connection of the intermediate and anchoring chains, a sprocket-wheel at the outer end of said steering-chain, and motion-transmitting gearing, by which the sprocket-wheel is caused 10' to travel along the anchoring-chain, so as to A. MUHLE, B. ROI.
